Description
Technical field
The present invention relates to the technology being managed to network system.
Background technology
As the technology for the high capacity for realizing the optical-fiber network using wave division multiplex transmission, elastic optical network receives much concern.
Non-patent literature 1 discloses the optimization of elastic optical network.
In existing fixed railing lattice optical-fiber network, the distribution of each light-path is converged in the sparse grid of centre frequency
Frequency band in frequency of heart interval.It is (193.1THz+ { 12.5,25,50,100 } × n GHz) in the sparse grid of centre frequency
In the case of, the centre frequency of grid converges on these centers frequency at intervals of (12.5,25,50,100GHz) to the distribution of each light-path
Frequency band in rate interval.
On the other hand, in elastic optical network, make centre frequency and frequency gap width variable, frequency can be distributed to each light-path
Band.One of variable centre frequency is (193.1THz+6.25 × n GHz), and one of variable frequency gap width is
(12.5GHz×m)。
Also, in elastic optical network, frequency raster width difference in the different light-path of asked frequency band is allowed in,
And it is different to be allowed in frequency raster width in the different light-path of modulation system.
Moreover, in elastic optical network, necessary minimal frequency resource is strictly distributed each light-path, therefore,
The utilization ratio of Internet resources can be improved.
In optical-fiber network, in addition to the situation via Wavelength converter, the frequency band for distributing to each light-path also be present
Must constant such restriction from initial point device to end-point arrangement.The restriction is referred to as the successional restriction of wavelength/frequency band." ripple
Length/frequency " means wavelength and frequency.
In the configuration of the light-path of the path for determining light-path and the frequency band for distributing to light-path, it is necessary to make to fill by transmitting
The frequency band of the light-path of wavelength-division multiplex link between putting does not compete mutually.
In elastic optical network, allow to be irregularly arranged light-path on the frequency axis, therefore, produce a large amount of untapped
Narrow-band may reduce as the frequency band that can house light-path, the utilization ratio of Internet resources.
The problem is known as following RSA problems：How foundation request for light-path determines transmission path,
How to distribute with frequency band obtained from frequency band unit divided band or frequency axis.RSA (registration mark) is Routing and
Spectrum Assignment (route is distributed with frequency spectrum) abbreviation.
As RSA ways to solve the problem, it is proposed that the automatic path for calculating light-path is simultaneously distributed making for light-path automatically
With the method for frequency.
By using Di Jiesite daraf(reciprocals of farad) and KSP algorithms in route searching, the automatic path for calculating light-path.Di Jiesi
Special daraf(reciprocal of farad) is the method for exporting the shortest path between initial point device and end-point arrangement.KSP algorithms be from shortest path successively
The method for calculating multiple paths.KSP is the abbreviation of k-shortest path (k bars shortest path).
The methods of by the path application First-Fit methods or Least-Used methods of light-path, light-path is distributed automatically
Frequency of use.First-Fit methods are the methods of wavelength/frequency minimum in the available wavelength/frequency of selection.Least-
Used methods are method of the selection using the wavelength/frequency of the minimum number of the link of wavelength/frequency.
As the method in the case of the foundation request that multiple light-pathes be present, patent document 2 proposes following method：Meter
The path of each light-path is calculated, the path of each light-path calculated is reset according to the ascending order of length, according to the order after rearrangement point
Frequency of use with each light-path.The frequency of use of each light-path is distributed using First-Fit methods.
Exist in light-path configuration and automatically configure and this 2 kinds of manual configuration.
In automatically configuring, path and the use of light-path are calculated automatically using routing algorithm and frequency allocation algorithm
Frequency.
In manual configuration, path and the frequency of use of light-path are manually selected by network application manager.
Automatically configure and have the following disadvantages.
With the manager of network to set according to light-path house handling capacity service priority predetermine wavelength/
Complicated restriction condition as frequency or circuitous path when being used for fault recovery using specific wavelength/frequency.
But this restriction condition is not accounted in automatically configuring, accordingly, it is possible to calculate desired path and using frequency
Rate.
Manual configuration has the disadvantage that：Manager need confirmed light-path via path in desired ripple
The whether continuous idle operation of length/frequency resource.Light-path via path mean light-path via relay and ripple
Divide multiplex link.
In existing fixed-grid optical-fiber network, the sparse grid center of a lattice frequency of centre frequency is converged on to light-path distribution
Frequency band in rate interval, therefore, manager assign wavelength numbering to centre frequency, confirm that whether assigned wavelength is numbered on road
It is continuous idle on footpath.
But in elastic optical network, required frequency band is different according to light-path, also, variable centre frequency and
Variable frequency gap width is taken as wavelength/frequency resource, it is thus identified that the operation whether desired wavelength/frequency resource is idle
Become miscellaneous.
